Polarisation-sensitive terahertz detection by multicontact photoconductive receivers
E. Castro-Camus, J. Lloyd-Hughes, M. B. Johnston +3
We have developed a terahertz radiation detector that measures both the amplitude and polarization of the electric field as a function of time. The device is a three-contact photoc…
Carrier dynamics in ion-implanted GaAs studied by simulation and observation of terahertz emission
J. Lloyd-Hughes, E. Castro-Camus, M. D. Fraser +2
We have studied terahertz (THz) emission from arsenic-ion implanted GaAs both experimentally and using a three-dimensional carrier dynamics simulation. A uniform density of vacanci…
Simulation and optimisation of terahertz emission from InGaAs and InP photoconductive switches
J. Lloyd-Hughes, E. Castro-Camus, M. B. Johnston
We simulate the terahertz emission from laterally-biased InGaAs and InP using a three-dimensional carrier dynamics model in order to optimise the semiconductor material. Incident p…
